I have two graphics cards on my laptop one is the Intel HD graphics card running from my intel i5 460M processor the other is an ATI Mobility Radeon HD5470. the intel one is the power saver graphics card and my laptop is permanently using that one ever since I swapped over to windows 8dp I was wondering if there was any way I could use the change to the ATI graphics card. On windows 7 there was an option to change between the two at any time but this seems to have dissapeared since installing windows 8dp.

Any help would be much appreciated
Cheers
